A team of researchers at the California Institute of Technology's Jet Propulsion Laboratory, working with a colleague from the University of Edinburgh, has found evidence suggesting that the Hunga Tonga-Hunga Ha'apai eruption ...
Natural gas (methane) can be converted into hydrogen (H2), which is used in clean energy, synthetic fertilizers, and many other chemicals. The reaction requires water and a nickel catalyst. Methane and water molecules attach ...
